Mark my confesion: It wasn’t intentional, it was quite accidental, my attention down rather than up. in my need to exclude the non-consenting general public I lopped off the cross at the top.

Wymondham Market Cross (absent the cross): 26th February 2019
Though neither round nor square, I claim this neither/nor octagon for the #2019picoftheweek title: Square/Round.

Wymondham Market Cross dates to 1617, when it replaced the previous cross that, alas, had been crisped and charred in a fire. The arsonists later paid their dues here (tried, sentenced and hanged).
Why a market cross? Well, these originally stood in the churchyard, where all markets, fairs, land transactions and marriages occurred … deals made in the sight of God were considered secure. But in C14th the Church got uppitty and said enough’s enough, there’s to be no more. And so the market crosses were moved to sites more secular. Some, like this one, then grew to be notable places. Here the guilds met. Here the taxes were paid. Here disputes were settled. And here the criminals tried.
The upper chamber now functions as the Tourist Information Office.
